Interactions between a mycorrhiza helper bacterium and arbuscular mycorrhizas

2009

Pseudomonas fluorescens C7R12 was shown to promote arbuscular mycorrhization and to act as a ‘Mycorrhiza Helper Bacteria’ (MHB). The complex interactions between this model strain, Arbuscular Mycorrhizal (AM) fungi and host-plants were analysed by assessing the specificity of these interactions and by characterizing bacterial cell organization on mycorrhizal roots. Evaluation of the interaction specificity relied on the comparison of the bacterial effect on (i) the in vitro saprophytic growth of Glomus mosseae and Gigasopora rosea and (ii) the root colonization of two different plant species (Medicago truncatula and Lycopersicon esculentum) by the two AM fungal species. Characterization of …

Is this fungus everywhere? Elucidating the genetic structure of populations of the arbuscular mycorrhizal fungus Glomus intraradices

2010

Arbuscular mycorrhizal fungi (Glomeromycota) are ubiquitous mutualistic associates of plants. Only relatively recently it has become possible to study the population biology of some species of these fungi. The model organism Glomus intraradices has been found across an extremely wide range of habitats and succession stages on different continents using molecular identification approaches. We used regions of the mitochondrially-encoded rDNA as novel molecular markers to resolve the intraspecies structure of G. intraradices and found a high diversity of mitochondrial haplotypes among isolates from all over the world. These markers for the first time also offer to genotype G. intraradices dire…

Arbuscular mycorrhiza : the biotrophic transportome from the cell to the field

2016

Understanding mechanisms underlying high nutrients use efficiency and carbon allocation in a context of mycorrhizal interactions is critical for sound management of croplands taking care of ecosystem services rendered by mycorrhizal fungi. Transport processes across the polarised membrane interfaces are of major importance in the functioning of the established mycorrhizal association as the symbiotic relation is based on a 'fair-trade' between fungus and host plant. Uptake and exchanges of nutrient and/or metabolites, at biotrophic interfaces are controlled by membrane transporters and their regulation patterns are essential in determining the outcome of plant fungal interactions and in ada…

BioVine project - Increase plant health through mycorrhizal fungi

2019

National audience; Organic vineyards still rely on large external inputs to control harmful organisms. BIOVINE will develop natural solutions based on plant diversity to control pests and reduce pesticide dependence. The capacity of plants of increasing the ecosystem resistance to pests and invasive species is a well-known ecosystem service. However, monocultures like vineyards do not exploit the potential of plant diversity. BIOVINE aims to develop new viticultural systems based on increased plant diversity within (e.g. cover crops) and/or around vineyards by planting selected plant species for the control of arthropods, soil-borne pests (oomycetes, fungi, nematodes), and foliar pathogens.…
